Title: Method and Apparatus for Smoothening the Surface of Shirred Food Casings
Inventor: WATTS KEITH ARTHUR
IPC: A22C13/02
Filed: 1995-08-29
Abstract: A method for treating a shirred food casing strand, having a diameter, a circumference, a longitudinal axis, an external surface and a hollow bore along at least a portion of  said longitudinal axis, which comprises smoothing said exterior surface by rolling said strand between at least three rollers, all of which simultaneously contact said surface at different lines of contact. It has been found that the simultaneous use of at least three different lines of contact during rolling,  as opposed to two lines of contact, as might be applied by rolling between plates, helps preserve and even improve the roundness of the strand.   The invention further comprises an apparatus for practicing the method of the invention which comprises at least three rollers arranged so as to contact the exterior surface of the strand and means for rolling the strand between said rollers.          The invention further includes a shirred food casing strand having an external surface simultaneously rolled at at  least three lines of contact.   The strand of the  invention has a smoothened exterior surface, and is straight and round.

Title: Reactions catalyzed by haloporphyrins
Inventor: ELLIS PAUL E JR
IPC: C07C51/265
Filed: 1995-08-30
Abstract: The  invention  provides  novel  methods  for  the  oxidation of hydrocarbons with oxygen-containing gas to form hydroxy-group containing compounds and for the decomposition of hydroperoxides to form hydroxygroup containing compounds.  The catalysts used in the methods of the invention comprise transition metal complexes of a porphyrin ring having 1 to 12 halogen substituents on the porphyrin ring, at least one of said halogens being in a meso position and/or the catalyst containing no aryl group in a meso position.  The catalyst compositions are prepared by halogenating a transition metal complex of a porphyrin.  In one embodiment, a complex of a porphyrin with a metal whose porphyrin complexes are not active for oxidation of alkanes is halogenated, thereby to obtain a haloporphyrin complex of that metal, the metal is removed from the haloporphyrin complex to obtain the free base form of the haloporphyrin, and a metal such as iron whose porphyrin complexes are active for oxidation of alkanes and for the decomposition of alkyl hydroperoxides is complexed with the free base to obtain an active catalyst for oxidation of alkanes and decomposition of alkyl hydroperoxides.

Title: Secure hand-held endometrial tissue sample collecting device
Inventor: THEODORU LIVIU
IPC: A61M1/00
Filed: 1995-09-13
Abstract: A hand held device comprising a sample collecting flask having a top mouth closed by a releasable closure cap,  and defining a top sample inlet and a bottom air outlet.  A first flexible rubber hose is removably plugged on the top inlet and is connected at its other end to a curette.   A second  flexible rubber hose  is removably plugged on the bottom outlet and is serially connected to a vacuum pump assembly via a buffer container.   A first rigid tube extends into the sample flask, being connected at one end to the top sample inlet, and opening into the sample flask spacedly proximate the bottom flooring of the sample flask.  A second rigid tube also extends into the sample flask, being connected at one end to the bottom air outlet and opening into the sample flask spacedly proximate the closure cap.  Therefore, the free extremities of the first and the second interior rigid tubes are vertically spaced apart.     When the vacuum pump is activated,  a negative pressure in the sample flask will be generated, producing a suction force in the curette for deposition of uterine wall fluid tissue sample inside the sample flask, exclusively of the air outlet hose.

IPC: F16D1/091
Filed: 1995-01-03
Abstract: A mounting device for anchoring a machine element (11) having a tapered bore (13) coaxially upon a rotary shaft (12).  The device fits between the tapered bore (13) and the cylindrical surface (14) of the shaft (12) and is effective to position the element at any desired position longitudinally  and at any angular position circumferentially of the shaft (12).  The device has inner (21) and outer (22) segmented sleeves, the mating surfaces of which are similarly tapered so that relative axial displacement of the sleeves (21, 22) effects expansion and contraction  of the interior bore and external surface of the combined elements.  Rotation of an internally threaded nut (23) at one end of the device effects the relative axial displacement of the inner (21) and outer (22) sleeves to afford expansion and contraction  of the outer sleeve (22) without straining the material of the sleeve or the nut (23).
